Cylindrical Roller Bearings FAG NU2214 -E-XL-TVP2

The FAG NU2214 -E-XL-TVP2 cylindrical roller bearing, with dimensions of 70 × 125 × 31 mm, is designed to withstand high radial loads as a separable, single-row idler bearing with a polyamide cage.

The NU2214 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for high radial loads. With a bore of 70 mm, an outside diameter of 125 mm and a width of 31 mm, this design functions as a classic idler bearing. Designs in industrial mechanical engineering utilise this type to compensate for thermal linear changes in shafts without restriction within the bearing. As the bearing is of an open design, the lubricant is supplied directly via the surrounding machine housing.

What is the NU2214 -E-XL-TVP2 cylindrical roller bearing suitable for?

Design engineers primarily use this cylindrical roller bearing at bearing locations where purely radial forces are present and axial shaft displacement must be permitted. Due to the NU design, the outer ring has two fixed flanges, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides, which simplifies handling during assembly and maintenance. When used in conjunction with a fixed bearing, the component supports radial shaft guidance at operating temperatures between –30 and +120 degrees.

What are the characteristics of the polyamide cage and the standard radial bearing clearance?

The integrated polyamide cage guides the rollers quietly and is characterised by its low weight. This choice of material reduces the inertial forces acting on the bearing during rapid changes in speed. The bearing is manufactured to standard radial bearing tolerances and complies with tolerance class P0 or ABEC 1. As the open design has no integrated seals, an external housing seal protects the raceways against dirt and moisture, preventing premature wear.
